Answer:

27, 13.5

Step-by-step explanation:

The area of a triangle is given by the following equation:

[tex]A=\frac{1}{2}bh[/tex]

where:

b is the base of the triangle

h is the height of the triangle

For the first triangle in this problem we have:

b = 6 is the base

h = 9 is the height

Therefore, the area of this triangle is:

[tex]A_1=\frac{1}{2}(6)(9)=27[/tex]

For the second triangle in this problem, we have:

b = 3 is the base

h = 9 is the height

Therefore, the area of this triangle is:

[tex]A_2=\frac{1}{2}(3)(9)=13.5[/tex]
